Good Golly!

Told you, that it was possible and not hard to do!!!!!!!!! The one at my teacher has, its baby looks more mollie like with a lyretial tail.

No one said you couldn't cross guppies with mollies kribensis12. What we were saying you certainly cannot do is cross a platy/swordtail with a molly/guppy - that cross simply won't work. Also, as you can see, there were no survivors - and this is typical of molly-guppy hybrids.

BTW, it's not because of mutations that occur during mitosis etc that these hybrids tend to die young - it's simple genetic incompatibility. The two species do not have the same genes in the same places so the crosses can only rarely function properly (it's a probability thing ).

Anyone trying to do this should use the smaller molly species and not sailfins. The purer they are, also, the easier it'll be. The more hybridized they are, the less likely the genes are to be compatible across the species. Also, BTW, the 'balloon' molly is not some seperate species. There are even balloon guppies (just as there are ballon rams and balloon kissing gouramies). It's a simple genetic mutation that arises in many different species.

Anyway - a very interesting project. I'd love to see the result of crossing male guppies with female mollies

Gee, that was unintelligent. Did you even read any of the other posts?

Sorry none of the gollies survived Darkmoon. I would definately like to see a take 2 some time, what you've gathered from the last attempt certainly leaves alot of hope for success. Best of luck to you.

I am sorry about the post, I said that because every one was telling me it was almost impossible to do and you did it on a first try. I am sorry about the loss of your fry darkmoon.

I began with two female guppies—blonde with red tails—from a reputable local store who kept males and females in separate tanks, and whose wholesaler did the same. I picked the two that looked youngest, barely sexually mature, and with the body shape typical of a livebearer who has never carried a litter. I then isolated them in a 2-gallon tank, alone, for the next 4 months. Neither ever developed a gravid appearance or dropped any fry.

Sorry Krib but what u did was not the same, Darkmoon Bettas worked to do this and resualted with nothing other than some good photo's and more idea's.

You said you just had the fish in a community and it just happened while it still possible the mother fish still had stored sperm from a male.

The fish u posted it looked like was a wild molly colour which u though was strange, but that only coz you never see wild coloured mollies in shops very often.

Like i told you befor if you set out to do it with vergin fish and documented it then their is no problems, but I've heard so many stories of crosses and their all normale fish, but noobs thinking they done something new when it's not.

Not saying your a noob befor u say it but theirnothing unless you document it and photograph them.

I have a female white molly that has never been exposed to a male. I raised her. She is almost mature enough to breed. Both of her parents were solid white along with all the siblings. Now I just need the right male.
I also have a female guppy. She is still too little though. I have the male for her in another tank.

I joined this forum exactly because of this post, so you should feel special.

Anyway, I'm extremely intrigued by this. I, too, once saw a picture and decided to try my luck. If you have any success with the male guppy/female molly cross, please do let me know. I tried this a while back. I had two male guppies and three female mollies. (Red male guppy, blue male guppy, dalmation molly, gold dust molly, black molly.) The male guppies were not interested in the girls AT ALL. I moved them into my tank of normal guppies and obtained young from them, so I know they weren't infertile. I saw them breed and display with the female guppies, but not the female mollies. I was actually kind of wondering if my endler/half black guppy cross males might work better. They are extremely "breedy" and would be smaller compared to the gold dust females and such. (You should see these crosses, they are gorgeous. The males are small like an endler, but a little bigger and they have a huge irredescent red/gold/blue stripe through the middle of their black tail. I have a poor quality pic of one somewhere if you'd be interested in seeing them.) I was thinking maybe these male guppies before weren't interested because they were actually a bit bigger than the female mollies and may have seen them as "too immature".

I never thought of trying the reverse cross like you did as I figured the male mollies would be too big. I will be sure to try this, though.

Thank you for such a wonderful post and such great pictures. Keep us posted!

Edit: I was just thinking...did you have these fish in brackish water? Guppies can tolerate saltwater, so if you had them in plain freshwater, I'd suggest making it brackish for the mollies. Maybe you would get better results this way? Might make the young a little more viable if they are in water more suitable for them.

id like to sugest putting the males in for a littlie longer and tryniog differant males because the size of mollie fry inside a guppie ive heard can kill

 

[Jozlyn]

What a facinating read.

Maybe I'll end up with some muppies or gollies one day as I have a female molly sharing with 5 male guppies! Someone else suggested that that was what I was trying to do by having them in the same tank, not true, at that time I didn't even consider that they might breed together. If the ever do it will be a long while before that will happen as she's just given birth and is no doubt still storing fertiliser for more!

 

[Rillan]

Ive read about this on other threads but never seen pictures. It is truly fascinating. Please please please post about hows it going!

 

[preDATor]

I got about 5 male guppy in with about 3/4 female gambusia who are being chased frantically by the male guppy's similar to when guppy's breed...gammies?

whats the likeliness of this happening?

 

[helterskelter]

firstly if you got G. affinis then your guppies will soon be killed!!!!

the gonopodium structure is totaly difI've never heard of this possibe crossferent, gambusia's gonopodium is more pointed, so the guppies may try but it's incorrect to space the sperm in the correct location.
Also these fish are totaly different so even if they managed to i would think their is less then a 5% chance of ever getting fry.

But i will admit i've never heard of anyone trying to cross these fish.

If your working from vergin fish, then this would be intresting to see what happens.

 

[mommyof2bettas]

great read
I would like to try this sometime, would be interesting!

just so you guys know when animals cross breed with other animals the father comes first in the naming. like liger is a male lion female tiger
gollies=male guppy female molly
muppies=male molly female guppy
coydog=male coyote female dog
and so on , i think you guys get the picture

i think the only exception are mules. just thought i'd add that bit of useless information

 

[mommyof2bettas]

Heh, I didn't know that, good to know, I like usueless nformation!
